I have many times suggested (or liked a post that suggested) people check out their senior centers for activities for their seniors. I now belong to a book discussion club at my senior center. (That makes 3 I belong to -- 38 books a year to discuss!). And today I joined a few ladies for lunch at a local restaurant. They meet monthly, at different places. When I walked in to attend the book club there were 2 tables set up with folks playing cards. I couldn't see what a third table was doing -- crafts, I think. So I'll say it again: If you are looking for activities for your elder, look into what is available at your community's senior center.
Wish my MIL would take advantage of the one by her, but she's so introverted, she has exactly the same number of friends she had 30 years ago: one.
Jeanne--good for you! It's hard to push into new things. But I could do 3 bookclubs!!
So Heeding your own advice will probably be very beneficial to you.
And hope others will also seek out what is offered at their senior centers. Hope you have fun.
